If you use an air conditioner in summer, be sure to turn on the AC button first.
You don't need to turn on the AC when driving in winter
You don't need to turn on the AC when you drive the air conditioner in winterFirst of all, it is necessary to understand that AC is the abbreviation of Aircondition, which is understood as air control or air conditioning, and is understood as the meaning of the air conditioner refrigeration switch in the car, which also represents the air conditioning compressor, so you need to turn on the AC when turning on the air conditioner in summer.
It is not the same to turn on the heater in winter, the heater is the use of the heat cycle inside the car, waste use,You don't need to turn on the AC key。If the AC is turned on, the load on the engine will increase after the air conditioning compressor is started, and the fuel consumption of the car will also increase.
Many models turn on the front windshield defogging function, and the car automatically turns on the AC, the reason is that the AC has a dehumidification function, which can speed up the efficiency of defogging. After the water temperature of the engine rises, when the heating function is turned on, the temperature in the car will gradually rise, although the absolute humidity in the space remains unchanged, but the high temperature causes the water molecules to move violently, so that the water molecules will not condense into fog, which achieves the effect of defogging.
To put it simply,Fuel consumption when opening AC and fuel saving when turning off AC;
The AC is heated quickly when the AC is turned on, and the AC is heated slowly when the AC is turned off.
Tips:
It is not advisable to turn on the heater as soon as you get in the car (AC off).Try not to turn on the heater as soon as it starts. In winter, the temperature of the water tank is very low after the engine is started, and turning on the warm air at this time will not only not blow out the warm air, but also prolong the heating time of the water.
Warm air should not be blown directly on the faceThe warm air blows directly on the face for a long time, which can easily make people feel tired and affect driving safety. When using warm air for a long time, a small slit should be left in the glass to allow air circulation and increase oxygen content.
Do not sleep in the vehicle while the vehicle is startingIt is dangerous to turn on the heating and close the windows when the vehicle is starting, and the air conditioning system can suck the incomplete products of gasoline combustion into the cabin, which can lead to the risk of poisoning or suffocation.
